I have a parameter that is set by the user in my starting method. but i need to use the value of that parameter in another method use later in the program. how can i move the parameter from one method to the other without asking the user for the value again? (i already tried the clipboard and it didn't work)

Since it's a number that is used by more than one method, it would be better suited as a world-class variable. Go to the properties tab of the world and create a variable which sets its value to whatever the user wants it to be at the start of the world. This way, you can have any method reference the variable at any time wthout worrying about passing values.
